Summary
As of May 12th, a total of 904 COVID-19 cases and 23 deaths (case fatality rate: 2.5%) have been reported in the Republic of Cyprus.
Among these cases, 20.9% are health-care workers (n = 189) - 4.3% physicians (n = 39), 10.5% nurses (n = 95), 1.4% other health occupations (n = 13), and 4.7% auxiliary staff (n = 42).
The median age of cases is 45 years (interquartile range - IQR: 32-59 years); 49.8% are female and 50.2% are male.
Overall, of 760 cases for which the place of exposure was known, locally acquired infections (index cases and close-contacts of confirmed cases) were 631 (83%) - of these 8.2% (n = 62) were related to a health-care facility (General Hospital in Pafos) and 12.7% (n = 80) were reported in Aradippou municipality.
In total, 19.1% (n = 173) of cases received hospital care, of which 135 (78%) have been discharged alive from the hospital. Median age of all hospitalized patients is: 62 years (interquartile range: 49-73 years), and 65.3% are males.
Four patients were still in intensive care units (for part of the day if they died, were discharged or transferred on that day or for the whole day, by May 12th); all of these were intubated.
Overall, 481 (53.2%) cases have recovered.
A total of 78,239 tests have been performed as of May 12th (8,932.4 per 100,000 population).
Data are subject to change due to the rapidly evolving situation 3
Epidemiological surveillance in the Republic of Cyprus
Analyses are based on laboratory-confirmed cases notified to the Epidemiological Surveillance Unit of the Ministry of Health.
As of May 12th, 904 laboratory-confirmed cases of coronavirus disease 2019 (COVID-19) have been reported (Figure 1 and 2).
The median time between symptoms onset and date of sampling was 4 days (Interquartile range - IQR: 2-7 days). It should be noted that for 14 cases the date of sample collection was before the onset of symptoms because of immediate testing of contacts of possible and laboratory-confirmed cases.
As of May 12th, the 14-day cumulative incidence rate of COVID-19 (per 100,000 population), a measure which reflects the number of active COVID-19 cases in the population (prevalence)1, is 7 per 100,000 population (Figure 3).
Figure 1: Number of laboratory-confirmed COVID-19-cases in Cyprus since 01/03/2020 by date of sample collection and date of symptoms onset (n = 904 and n = 477 with data available, respectively). Recent data should be interpreted with caution due to the possibility that cases with date of onset within the reporting period have not yet been diagnosed.

Epidemiological link As of May 12th, place of exposure is available for 760 cases (84.1%). In total, 17% (n = 129) of laboratory-confirmed COVID-19-cases had history of travel or residence abroad during the 14 days prior to symptom onset (imported). These cases have a direct link to the UK and Greece, mainly. Locally acquired infections (index cases and close-contacts of confirmed cases) occurred in 83% (n = 631 of 760 with known place of exposure) of the cases, of which 8.2% (n = 62) were related to a health-care facility (General Hospital in Pafos). Of all cases in Aradippou (Larnaka district) (n = 123), 80 (65%) were locally-acquired, 10 (8.1%) imported and for 33 cases (26.8%) the epidemiological link was not recorded at the moment. Table A1 in the appendix shows the number and the rate (per 100,000 population) of locally-acquired cases by district of residence.
2 The term “health-care worker” is based on the occupation and not on the place of exposure. Health-
care workers are defined as all health care professionals, allied health workers, and auxiliary health
workers.

shortness of breath (105/862; 12.2%). Other reported symptoms were diarrhoea, runny nose, and headache. Table A2 in appendix reports the sex and age distribution of asymptomatic cases at diagnosis.
Pre-existing conditions Information on comorbidities was available for 795 (87.9%) cases. Of these, 325 (40.8%) reported at least one comorbidity. The most commonly reported comorbidities were:
hypertension (126/788; 16%),
diabetes (72/769; 9.4%),
heart disease (62/790; 7.8%), and
cancer (24/795; 3%). Other reported comorbidities were chronic kidney disease, autoimmune disease, and chronic respiratory disease.
Data are subject to change due to the rapidly evolving situation 8
Deaths As of May 12th, 23 deaths were reported in Cyprus (Case Fatality Rate - CFR: 2.5%). The mortality rate for COVID-19 is 2.6 per 100,000 population. Seventeen deaths (73.9%) occurred in men and six (26.1%) in women; the median age of all deaths was 76 years (IQR: 66-79 years). Nine deaths were reported among residents in Larnaka, six in Pafos, three in Nicosia and Ammochostos, each, and two in Limassol (Appendix Table A3). The median time from date of sampling to death was 8 days (IQR: 4-18 days). Figure A3 shows the Kaplan-Meier curve of the time from date of sampling to death. For 16 deaths, COVID-19 was the underlying cause of death (COVID-19 CFR: 1.8%). Figure 5 reports the number of deaths by date.

Hospitalization and intensive care unit (ICU) admissions3 In total, 19.1% (n = 173) of people with COVID-19 received hospital care, and 135 patients (78%) have been discharged alive from the hospital. The median age of hospitalized patients was 62 years (IQR: 49-73 years). Hospitalized cases were mainly males (n = 113; 65.3%). Figure 6 shows the total number of hospital admissions by date.
Figure 6: Number of laboratory-confirmed COVID-19 cases by date of hospital admission (n = 173). * Date of hospital admission; for inpatients hospitalised prior to the beginning of the epidemic, it was replaced with date of sampling.
Overall, 32 cases (18.5% of all hospitalized patients) have been admitted to ICU4, of which 4 were still in ICU (as of May 12th). A total of 27 ICU patients (84.4% of all ICU patients) have been intubated, of which 4 (100% of all patients currently in ICU) are still intubated. The overall median length of stay in ICU (for all 32 ICU cases, considering those still in ICU until May 12th) was 11 days (IQR: 8-27.5 days). Figure A4 shows the Kaplan-Meier curve of the length of stay in ICU.
3 Data on hospitalisation and ICU are provisional and should be interpreted with caution because delay
in data reporting is likely; for the construction of the curve, people are no longer in an ICU the day next
to the date of their discharge, death or transfer. 4 Intensive care unit (ICU) refers only to the ICU in Limassol General Hospital and to the ICU in Nicosia
General Hospital.

For patients who died while in ICU (n = 15), the median length of stay in ICU was 10 days (IQR: 3-20). Figure A5 shows the Kaplan-Meier curve of the length of stay in ICU for the people who died. For patients transferred/discharged alive from ICU (n = 13), the median length of stay in ICU was 10 days (IQR: 8-27 days). The median age of patients ever admitted to ICU was 65.5 years (IQR: 56-75 years). ICU patients are mainly male (n = 23; 71.9%). The number of cases currently in ICU is 0.5 per 100,000 population. For comparison, Italy and Lombardia reported the highest rates of 6.7 per 100,000 population (n = 4,068) and 13.8 per 100,000 population (n = 1,381) on April 3rd. The ICU rates in Italy and Lombardia on May 12th are 1.6 per 100,000 population (n = 952) and 3.2 per 100,000 population (n = 322) (https://github.com/pcm-dpc/COVID-19/blob/master/dati-andamento-nazionale/dpc-covid19-ita-andamento-nazionale-20200512.csv; https://github.com/pcm-dpc/COVID-19/blob/master/dati-regioni/dpc-covid19-ita-regioni-20200512.csv).

5 For symptomatic cases, or for cases hospitalised, a COVID-19 case can be considered cured after the
resolution of symptoms and two negative tests for SARS-CoV-2 at 24-hour interval at least.
For asymptomatic cases, or for persons isolated at home, the negative tests to document virus clearance
should be obtained at a minimum of 14 days after the initial positive test (end of the quarantine period).
